LC_COLLATE: Fix last character ellipsis handling (Bug 22668)
During ellipsis processing the collation cursor was not correctly moved to the end of the ellipsis after processing. The code inserted the new entry after the cursor, but before the real end of the ellipsis: [cursor] ... element_t <-> element_t <-> element_t <-> element_t "<U0000>" "<U0001>" "<U007F>" startp endp At the end of the function we have: [cursor] ... element_t <-> element_t <-> element_t "<U007E>" "<U007F>" endp The cursor should be pointing at endp, the last element in the doubly-linked list, otherwise when execution returns to the caller we will start inserting the next line after <U007E>. Subsequent operations end up unlinking the ellipsis end entry or just leaving it in the list dangling from the end. This kind of dangling is immediately visible in C.UTF-8 with the following sorting from strcoll: <U0010FFFF> <U0000FFFF> <U000007FF> <U0000007F> With the cursor correctly adjusted the end entry is correctly given the right location and thus the right weight. Retested and no regressions on x86_64 and i686. Co-authored-by: Carlos O'Donell <carlos@redhat.com>
